Zusammenfassung:A single adjustment phase resolver uses common voltage control in a dual inversely tracking bridged-Tee attenuator circuit (21) to provide a variable relative phase displacement between two output signals whose amplitude levels are maintained equal and constant throughout the range of the phase adjustment. The dual bridged-Tee attenuator is implemented using two variolossers wherein the PIN diodes are serially connected in two pairs (51 and 52, 53 and 54) and the pairs are oppositely poled from one another. An automatic gain control circuit (16, 24 and 26) adjusts the input signal level to compensate for a latitude of discrepancy between the inverse tracking variolossers.
